53a92889ec net: bcmgenet: add missed clk_disable_unprepare in bcmgenet_probe 
The driver forgets to call clk_disable_unprepare() in error path after
a success calling for clk_prepare_enable().

Fix to goto err_clk_disable if clk_prepare_enable() is successful.

1cfd3426ef ath10k: Fix NULL pointer dereference in AHB device probe 
This fixes a NULL pointer dereference in the probe path for AHB devices.
There attr parameter in the ath10k_ce_alloc_pipe() function is not
initialized, but accessed. This function is called by
ath10k_pci_setup_resource() which is called by ath10k_ahb_probe().

The struct ath10k_pci is also used for AHB devices and not only for PCI
devices.

The initialization of the new members of struct ath10k_pci is moved to
ath10k_pci_setup_resource() which is used by the PCI and the AHB code.

This also fixes a use after free bug in ath10k_pci_remove() when ar_pci
is accessed after ath10k_core_destroy() was called, which calls
ieee80211_free_hw() and frees this memory.

This fixes the following bug seen with backports-5.8-rc2 on OpenWrt on a
IPQ4019 device:

The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked.  Shift amounts greater than or equal to 32 will result in
undefined behavior.  Add code to deal with this.

used as a right shift amount for other bitmask values without being
checked.  Shift amounts greater than or equal to 32 will result in

for invalid channels so that enabled channel bits that would have been
lost by shifting are also checked for validity.  Only channels 0 to 15
are valid.

0bd0db42a0 staging: comedi: addi_apci_1032: check INSN_CONFIG_DIGITAL_TRIG shift 
The `INSN_CONFIG` comedi instruction with sub-instruction code
`INSN_CONFIG_DIGITAL_TRIG` includes a base channel in `data[3]`. This is
used as a right shift amount for other bitmask values without being
checked.  Shift amounts greater than or equal to 32 will result in
undefined behavior.  Add code to deal with this.

f07804ec77 staging: comedi: ni_6527: fix INSN_CONFIG_DIGITAL_TRIG support 
`ni6527_intr_insn_config()` processes `INSN_CONFIG` comedi instructions
for the "interrupt" subdevice.  When `data[0]` is
`INSN_CONFIG_DIGITAL_TRIG` it is configuring the digital trigger.  When
`data[2]` is `COMEDI_DIGITAL_TRIG_ENABLE_EDGES` it is configuring rising
and falling edge detection for the digital trigger, using a base channel
number (or shift amount) in `data[3]`, a rising edge bitmask in
`data[4]` and falling edge bitmask in `data[5]`.

If the base channel number (shift amount) is greater than or equal to
the number of channels (24) of the digital input subdevice, there are no
changes to the rising and falling edges, so the mask of channels to be
changed can be set to 0, otherwise the mask of channels to be changed,
and the rising and falling edge bitmasks are shifted by the base channel
number before calling `ni6527_set_edge_detection()` to change the
appropriate registers.  Unfortunately, the code is comparing the base
channel (shift amount) to the interrupt subdevice's number of channels
(1) instead of the digital input subdevice's number of channels (24).
Fix it by comparing to 32 because all shift amounts for an `unsigned
int` must be less than that and everything from bit 24 upwards is
ignored by `ni6527_set_edge_detection()` anyway.

544f287b84 bonding: check error value of register_netdevice() immediately 
If register_netdevice() is failed, net_device should not be used
because variables are uninitialized or freed.
So, the routine should be stopped immediately.
But, bond_create() doesn't check return value of register_netdevice()
immediately. That will result in a panic because of using uninitialized
or freed memory.

Test commands:
    modprobe netdev-notifier-error-inject
    echo -22 > /sys/kernel/debug/notifier-error-inject/netdev/\
actions/NETDEV_REGISTER/error
    modprobe bonding max_bonds=3

7c6719a1aa arm64: dts: clearfog-gt-8k: fix switch link configuration 
The commit below caused a regression for clearfog-gt-8k, where the link
between the switch and the host does not come up.

Investigation revealed two issues:
- MV88E6xxx DSA no longer allows an in-band link to come up as the link
  is programmed to be forced down. Commit "net: dsa: mv88e6xxx: fix
  in-band AN link establishment" addresses this.

- The dts configured dissimilar link modes at each end of the host to
  switch link; the host was configured using a fixed link (so has no
  in-band status) and the switch was configured to expect in-band
  status.

With both issues fixed, the regression is resolved.

fad58190c0 net: dsa: mv88e6xxx: fix in-band AN link establishment 
If in-band negotiation or fixed-link modes are specified for a DSA
port, the DSA code will force the link down during initialisation. For
fixed-link mode, this is fine, as phylink will manage the link state.
However, for in-band mode, phylink expects the PCS to detect link,
which will not happen if the link is forced down.

There is a related issue that in in-band mode, the link could come up
while we are making configuration changes, so we should force the link
down prior to reconfiguring the interface mode.

This patch addresses both issues.

5714ee50bb copy_xstate_to_kernel: Fix typo which caused GDB regression 
This fixes a regression encountered while running the
gdb.base/corefile.exp test in GDB's test suite.

In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area.  Thus the
correct mask corresponding to XCR0 was not present in the core file for
GDB to interrogate, resulting in the following behavior:

1ad2405833 net/smc: fix restoring of fallback changes 
When a listen socket is closed then all non-accepted sockets in its
accept queue are to be released. Inside __smc_release() the helper
smc_restore_fallback_changes() restores the changes done to the socket
without to check if the clcsocket has a file set. This can result in
a crash. Fix this by checking the file pointer first.

741a49a4dc net/smc: do not call dma sync for unmapped memory 
The dma related ...sync_sg... functions check the link state before the
dma function is actually called. But the check in smc_link_usable()
allows links in ACTIVATING state which are not yet mapped to dma memory.
Under high load it may happen that the sync_sg functions are called for
such a link which results in an debug output like
   DMA-API: mlx5_core 0002:00:00.0: device driver tries to sync
   DMA memory it has not allocated [device address=0x0000000103370000]
   [size=65536 bytes]
To fix that introduce a helper to check for the link state ACTIVE and
use it where appropriate. And move the link state update to ACTIVATING

b9979c2e83 net/smc: fix handling of delete link requests 
As smc client the delete link requests are assigned to the flow when
_any_ flow is active. This may break other flows that do not expect
delete link requests during their handling. Fix that by assigning the
request only when an add link flow is active. With that fix the code
for smc client and smc server is the same, so remove the separate
handling.

c48254fa48 net/smc: move add link processing for new device into llc layer 
When a new ib device is up smc will send an add link invitation to the
peer if needed. This is currently done with rudimentary flow control.
Under high workload these add link invitations can disturb other llc
flows because they arrive unexpected. Fix this by integrating the
invitations into the normal llc event flow and handle them as a flow.
While at it, check for already assigned requests in the flow before
the new add link request is assigned.

63673597cc net/smc: protect smc ib device initialization 
Before an smc ib device is used the first time for an smc link it is
lazily initialized. When there are 2 active link groups and a new ib
device is brought online then it might happen that 2 link creations run
in parallel and enter smc_ib_setup_per_ibdev(). Both allocate new send
and receive completion queues on the device, but only one set of them
keeps assigned and the other leaks.
Fix that by protecting the setup and cleanup code using a mutex.

only the qp_num but also the gid and the mac of the links. If there are
equal qp_nums for different links the wrong link would be chosen.

 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
 
 Some of the most recent, experimental distros are failing, fixes will be
 provided, but those gcc/clang versions are not yet in general use and some
 are related to linking with libllvm, not the default build.

Merge tag 'perf-tools-fixes-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into master

Pull perf tooling fixes from Arnaldo Carvalho de Melo:

 - Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.

 - Set opt->set in libsubcmd's OPT_CALLBACK_SET(). This fixes
   'perf record --switch-output-event event-name' usage"

Linus Torvalds
efb9666e90 A pile of fixes for x86: 
- Fix the I/O bitmap invalidation on XEN PV, which was overlooked in the
    recent ioperm/iopl rework. This caused the TSS and XEN's I/O bitmap to
    get out of sync.
 
  - Use the proper vectors for HYPERV.
 
  - Make disabling of stack protector for the entry code work with GCC
    builds which enable stack protector by default. Removing the option is
    not sufficient, it needs an explicit -fno-stack-protector to shut it
    off.
 
  - Mark check_user_regs() noinstr as it is called from noinstr code. The
    missing annotation causes it to be placed in the text section which

 "A pile of fixes for x86:

   - Fix the I/O bitmap invalidation on XEN PV, which was overlooked in
     the recent ioperm/iopl rework. This caused the TSS and XEN's I/O
     bitmap to get out of sync.

   - Use the proper vectors for HYPERV.

   - Make disabling of stack protector for the entry code work with GCC
     builds which enable stack protector by default. Removing the option
     is not sufficient, it needs an explicit -fno-stack-protector to
     shut it off.

   - Mark check_user_regs() noinstr as it is called from noinstr code.
     The missing annotation causes it to be placed in the text section
     which makes it instrumentable.

   - Add the missing interrupt disable in exc_alignment_check()

66e4b63624 Two fixes for the timer wheel: 
- A timer which is already expired at enqueue time can set the
    base->next_expiry value backwards. As a consequence base->clk can be set
    back as well. This can lead to timers expiring early. Add a sanity check
    to prevent this.
 
  - When a timer is queued with an expiry time beyond the wheel capacity
    then it should be queued in the bucket of the last wheel level which is
    expiring last. The code adjusts expiry time to the maximum wheel
    capacity, which is only correct when the wheel clock is 0. Aside of that
    the check whether the delta is larger than wheel capacity does not check
    the delta, it checks the expiry value itself. As a result timers can
    expire at random.
 
    Fix this by checking the right variable and adjust expiry time so it
    becomes base->clock plus capacity which places it into the outmost
    bucket in the last wheel level.

9413cd7792 Two fixes for the interrupt subsystem: 
- Make the handling of the firmware node consistent and do not free the
    node after the domain has been created successfully. The core code
    stores a pointer to it which can lead to a use after free or double
    free.
 
    This used to "work" because the pointer was not stored when the initial
    code was written, but at some point later it was required to store
    it. Of course nobody noticed that the existing users break that way.
 
  - Handle affinity setting on inactive interrupts correctly when
    hierarchical irq domains are enabled. When interrupts are inactive with
    the modern hierarchical irqdomain design, the interrupt chips are not
    necessarily in a state where affinity changes can be handled. The legacy
    irq chip design allowed this because interrupts are immediately fully
    initialized at allocation time. X86 has a hacky workaround for this, but
    other implementations do not. This cased malfunction on GIC-V3. Instead
    of playing whack a mole to find all affected drivers, change the core
    code to store the requested affinity setting and then establish it when
    the interrupt is allocated, which makes the X86 hack go away.

da05b143a3 x86/boot: Don't add the EFI stub to targets 
vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.

This confuses Makefile.build which interprets the EFI stub as a target
	$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]

Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.

58ac3154b8 x86/entry: Actually disable stack protector 
Some builds of GCC enable stack protector by default. Simply removing
the arguments is not sufficient to disable stack protector, as the stack
protector for those GCC builds must be explicitly disabled. Remove the
argument removals and add -fno-stack-protector. Additionally include
missed x32 argument updates, and adjust whitespace for readability.

Fixes: 20355e5f73 ("x86/entry: Exclude low level entry code from sanitizing")

85ebb8eb12 media: atomisp: move system_local consts into a C file 
Instead of declaring all those consts everywhere when the
headers are included, just place them on a single place.

This change shuts up lots of warnings when built with W=1:

08b2bcc665 media: atomisp: get rid of version-specific system_local.h 
After removing the unused 32-bits data, the isp2401_system_local.h
now contains everything that it is needed, either by isp2401 or
by isp2400.

So, remove code duplication.
